Re: [Freesurfer] manual parcellation of labels
Hi Aviinas, you could draw the label directly on the inflated surfaces, then use mri_label2label to map it from one subject (or the average) to the others. cheers, Bruce On Tue, 25 Jan 2005, Ketwaroo, Gyanprakash Avinash wrote: Hi, I want to divide my cingulate labels into anterior and posterior cingulate labels. This divison is based on a line perpendicular to the AC-PC axis, and through the AC. Currently, I am trying to do this by using csurf and clicking and saving points along the Tal = 0 coordinate within the midsagittal plane of the tkmedit view. I then go to the points in the tksurfer view and then draw a line here to create a new label. It seems that there must be an easier way of doing this using the code that csurf employs to link the volume and surface coordinates. If you could suggest a method for automating this, I would greatly appreciate it.

[Freesurfer] manual parcellation of labels
Title: manual parcellation of labels Hello, I guess my main question is are the volume tal coordinates in tkmedit equivalent to the vertex Tal in tksurfer. That is, can I ignore drawing the line in tkmedit and converting with csurf, and just trace out the Tal = 0 line in tksurfer? I think this is what you are implying but just want to make sure. Also, the cingulate labels are in RAS coordinates. Is there a quick way to convert the Tal=0 coordinate to a RAS coordinate so that I can just divide the cingulate label by applying a condition (eg RAS x) rather than tracing it out in tksurfer. Thank you for all your help.
